Abstract
The objective of this project is to propose a new 3D reconstruction technique of scoliotic spines, referred to as the “fast method”. In this technique, only five to eight points located on the overall shape of the spine, including the inferior and superior endplates centers of T1 and L4 vertebrae, are digitized on the frontal and lateral radiographs of the patient, so that the spline modeled curve joining these points meets the endplates centers along the spine in an optimal way. This curve is then classified on each view based on the scoliotic curve type and its severity using mathematical and clinical criteria. An average model, corresponding to the identified type and severity, is then used to estimate the 2D coordinates of the six anatomical landmarks per vertebra on the frontal and lateral planes. The DLT algorithm is then used to calculate the 3D coordinates of these six anatomical landmarks. This method, mainly because of its rapidity, is aimed to provide the clinician with a fast 3D visualization of his patient's spine directly during the visit in clinics. (Abstract shortened by UMI.)
